Sclerosing polycystic adenosis of the oral cavity.

Minor salivary glands are ubiquitous in the oral cavity, and related diseases are often indolent and asymptomatic. We describe the unusual features of sclerosing polycystic adenosis, and its similarities to more sinister conditions of the minor salivary glands. Its importance is currently uncertain and research points to a pathogenesis that is neoplastic, which can create ambiguity. Sclerosing polycystic adenosis is a newly-discovered condition that merits further discussion and research to evaluate its full impact.
